Google App Engine
PHP on App Engine available for everyoneRate Topic:

One early adopter of App Engine for PHP was VICE.com, who run the popular Motherboard blog. Motherboard receives millions of visitors a month, and runs on a long serving in-house CMS powered by the popular Yii PHP framework. Having moved Motherboard fully over to Google App Engine recently, “It's our opinion at VICE that Google is building the next generation PaaS,” said VICE.com CTO, Jesse Knight. “We're extremely excited to be early adopters.”
